Senior prison officials at the Arctic penal colony where the Russian opposition figure Alexei Navalny was detained and died will be banned from the UK and have their assets frozen, under sanctions announced by David Cameron.

The UK foreign secretary imposed sanctions on six individuals in response to Navalny’s death, which has been widely blamed on the Kremlin.
